Not all aftermarket magazines are created equal, and that’s one thing we can definitely confirm. Many companies that have entered the industry, trying to gain market share in the oversaturated magazine space, simply don’t deliver what consumers want. KCI USA (KCI) is not one of those companies.

The main driver of aftermarket magazine demand usually comes down to cost. However, most people agree it’s not worth saving a few bucks to have a magazine that can’t function or you need to replace after a few hundred rounds. 

This is where we see a select few manufacturers, KCI being one of them, stand out and maintain market share. 

Who Is KCI?

KCI started producing magazines in 1984 in South Korea. Since then, it has brought some of its manufacturing to the United States, but its focus has remained the same: delivering high-performing magazines at affordable prices.

Most notable for its AR-15, Glock, AK-47, and MP5 magazines, you can often count on them as one of the more reliable aftermarket options. Of course, if you want maximum reliability, you go with factory magazines, but you’ll have to pay a premium. That said, we do recommend factory magazines for any defensive firearms. But we digress…Back to KCI!

Since we’ve found KCI to be a popular option among our customers, we’ve made sure to stock a wide selection of its magazines.

AR-15 Magazines

We all love our AR-15s, right? You know what goes perfectly with an AR-15? Drum magazines! 

KCI offers 50-round and 100-round AR drum magazines, which allow you to keep your range day fun flowing or to maximize your home defense capabilities. The 100-round drum may be a bit heavy and unwieldy, but the 50-round should feel just right.

KCI Drummags

KCI is well-known for its drum magazines. Source

If drum mags are a little bit too much for your intended uses, you can always opt for the standard 30-round magazines, in either translucent polymer or black polymer with a window, or go even a little smaller to a 21-round translucent magazine

Steel mags and AKs go together like peanut butter and jelly. Source

Heat-treated steel construction paired with high-carbon steel springs and anti-tilt followers makes KCI’s AK magazines extremely durable and reliable. With all-steel construction and capacities pushing the limits, it’s important to remember the added weight your setup will have. Depending on your AK’s intended role, you’ll want to keep that in mind.

MP5 Magazines

You don’t want to settle for just any old magazine for your MP5. The last thing you’ll feel like you’re doing with KCI’s MP5 magazines is settling. 

With an all-steel construction featuring a Cation Electrodeposition coating, the durability is unparalleled. The locking plates are even spot-welded in four places to ensure top-notch strength.

Rounding out some of the popular pistol platforms, KCI offers magazines for 1911s, the Beretta 92FS, and the B&T APC9. We can’t forget the straggler rifle platforms like the M1 and  M1A/M14. KCI does a great job of sticking to what it does best while still offering a decent variety of offerings to cater to a majority of the consumer market.

What’s Next For KCI?

We don’t have any secrets to share, but if we had to guess, there will be some rimfire and/or AR-10 magazines coming soon. They are the two platforms that are popular and being requested enough to hopefully push KCI to expand its product line.

Until we see what’s next, we’ll continue fueling our range days with plenty of KCI’s extended mags and drums. Keep your eyes peeled for new KCI mags to be stocked as soon as they are released in the future, as we plan to continue to provide the best selection online!
